Statistics Window
Through Metrics -> Show stats window you can call a separate window, which provides some data about retinal image.
The window shows you the data at the moment as you open it.
Static data here is:
- Total number of cones
- CDC coordinates in pixel
- CDC density value in selected units
- PCD coordinates in pixel
- PCD coordinates in given units
Dynamic data (depending on the current cursor position) here is:
- Current cursor position coordinates
- Brightness value. Images of retina usually are greyscale images, so it shows value of exact pixel under cursor
- Density value in given units
- Density radial value in given units
Also, you can see the radial average plot in given units. Starting point is CDC.
Each point of the plot is calculated as average of all density values, which lie on the edge of a circle with given radius.
- Blue curve - the plot itself
- Red cross - the position on the plot, which is corresponds to the cursor position on the image
- Black vertical line - the approximation edge. All values before that line calculated as average of a full circle, after that we have missing parts of the circle. For example: we have rectangular image; radial average for the farthest corner pixel from CDC will density value at that pixel itself.
Units can be selected in the Units Settings window.
